CONVERTiBLE COT AND SEAT.

SPECIFICATION forming part of Letters Patent No. 339,131, dated April6,1886.

Application filed January 28, 1886.

T0 aZZ whom, it may concern:

Be it known that l, LYMAN BANKS, a citizen of the United States ofAmerica, residing at Muscatine, in the county of Muscatine and State ofIowa, have invented certain new and useful Improvements in ConvertibleCots and Seats, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to convertible cots and seats; and it consists ofan ordinary crosslegged cot constructed to be readily converted from acot into a seat, and vice versa, as hereinafter set forth.

In the accompanying drawings, Figure 1 is a perspective view of thedevice adjusted in position for use as a cot. Fig. 2 is a perspectiveview ofthe cot converted into a seat. Fig. 3 is an end elevation of thecot. Fig. 4 is an end view of the cot converted into a seat. Fig. 5 is adetached view of the coupling-bolt.

A A designate the rails of the cot, and B B the cross-legs, which aresecurely attached to the rails in any suitable manner.

0 designates the ordinary covering of the cot, made of canvas or anysuitable fabric, attached to the rails in the usual manner.

D designates the seat-supports, made of wood or any other suitablematerial, having one end pivoted by bolts or screws to thelegs B, nearthe rail A, the other ends of the supports being free and adapted tocatch as pawls in the notches in the legs.

The cross-legs B B are each provided with two round holes,c d,and slotsof less diameter than the holes and communicating with them, formingkeyhole-shaped openings, to receive the bolts f, provided on their endswith the locking-bits or angular projections h, the bolts being madelong enough to extend through both legs, so that the hooks will catchand hold against the inner surface of the crosslegs.

The legs 13 are provided with notches a, in which the free ends of thesupports D rest when the device is used for a seat. The cot bolt-holes care located, as usual, about the central portion of the legs, and theseat belt holes 01 are located in relation to the cot boltholes so thatwhen the device is converted into a seat the front rail, A, will be theprop- Serial No. 190.06.). (No model.)

er height for a seat, and the back rail, A, will be in proper positionto form a seat-back, as shown. Ordinarily, for this purpose, the seatbolt-holes d are located in the leg B. supporting the back rail, A,about one-tenth of the length of the leg below the cot boltholes 0, andin the leg B, supporting the front or seat rail, A, the seat bolt-holesare about one-iifth the length of the leg above the cot bolt'holes c. Itis evident that the relative positions of these bolt-holes may be variedto obtain any required height of the seat-rail and inclination of theback of the seat.

The seat-supports D are made the required length, so that when used fora seat the free ends rest in thenotches a in the legs B,for the purposeof holding the rail A in position to allow the cover 0 to sasufficiently to form a comfortable seat, as shown in Figs. 2 and 4.;also to give firmness and strength to rail A. hen the device is used asa cot,the supports D are pendent.

To convert the cot into a seat,the bolts f are placed in the holes d,the free ends of the sup ports D being adjusted in the notches a, andthe frame and covering take the position shown in Figs. 2 and l.

The cross-legs are securely coupled together by means of the boltsf,having the angular bits or hooks h, which, by turning the bolts partlyaround, after being inserted through both legs, catch and hold againstthe inner surfaces of the inner legs.

It is evident that in coupling the crosslegs the coupling-bolts to beinserted or removed must be placed in position for the locking bits orhooks h to be in range with the slots. Thus it is shown that by verysimple and inexpensive devices an ordinary cross-legged cot is readilyconvertible into a convenient and comfortable seat, which is readilyconvertible back again into a cot.

What I claim as new, and desire to secure by Letters Patent, is

1. In a convertible frame, the combination of the supporting-legs B B,each provided with bolt-holes c (1, located in positions relative toeach other, as set forth, and the coupling-bolts f, adapted to couplethe legs together, to form a cot or a seat frame, substantially as andfor the purposes described.

2. lhe combination of the rails A A, the supports D, substantially asand for the pun legs B B, provided with the keyhole open- ,posesdescribed.
